Enamel slip properties

The consistent liquid enamel slip properties is a critical parameter at any automated wet application process.

Unfortunately enamel rheology is known to change easily under the influence of particle size, specific weight, temperature, milling additives and/or pretreatment chemicals.

Failure to maintain its properties within measurable tolerances, may result in inconsistent enamel layer thickness and eventually even enamel defects.

Do you really believe that you can “feel it” with your fingers as demonstrated on the picture below, or do you rather prefer a more precise testing method ?!

Ultrasonic thickness measurement

With ultrasonic thickness measurement, you may detect the thickness of individual layers within a multi layer coating.

This may be of great help, when troubleshooting e.g. a two coats / one fire vitreous enameling process.

See our webshop for more details about this and other film thickness gauges.

Automatic enameling plant for water heaters

Depending upon the annual production volume, it might be interesting to reduce labor cost by integrating all equipment of an enameling plant for water heaters and/or solar boilers.

Such integration may be done with traditional monorail conveyors in combination with automatic transfer devices, like on the picture below.

Alternatively a so-called power & free conveyor system may be used.

This conveyor type consist of two conveyor tracks above each other.

Example of power and free conveyor

On the lower level free cars may run, while via the power chain at the upper level the free cars may be (dis)connected and transported.

Nowadays there are P+F systems, which thanks to a very special transfer system even include the transport of products within the enameling furnace.
